iiVPROVENlENT IN TOP-PLATES FOR COOKING-STOVES.

Specification forming part oi' Letters Patent No. 141,838, dated August 12, 1873 application led June 14, 1873.

To all whom it may concern:

Be it known that I, JOHN VAN, of Cincinnati, Ohio, have invented an Improved rlop- Plate for Stoves and Ranges, of which the fol lowing is a specification:

My invention is designed to prevent the warping ot' the top-plate of a stove or range, and particularly of that portion which is situated immediately over the lire. For this purpose I form in one piece or casting with said plate a duct or hollow rib, solooated on the under side of said plate as to stiften those parts most liable to sag or warp, and at the same time to conduct smoke, &c., from the cooler portions near the sides of the fire-space and deliver them into the hotter portions so as to maintain a nearly equal temperature at This duct or hollow rib being, with its openings, wholly on the under side of the plate, and east solidly thereto, is invisible from above, and is not liable to have its inlets choked with matter falling upon the stove, nor obstructed by pots or other objects placed upon the top thereof.

Figures 1 and 2 are under-side views of two forms of top-plates of a cooking-range with my improvement. Figs. 3 and 4 are sections in the lines x .fr and y y, respectively.

A represents the top-plate proper.

" duct, tunnel-way, or hollow rib, cast 'to the Bisa n under surface of said plate, and having its openings wholly at the ends of the rib and on said under side of the plate, and so located as to communicate at their inlets or receivingends with those portions of the tire-space near the sides of the stove, and consequently with the comparatively cool portions of said space and at their outlets with the hotter central portions of said space, so as to insure constant passage of the cooler gases in the direction indicated by arrows, by maintenance of a nearly equal temperature at all parts of the plate, which, in conjunction with the stiffening effect of the said hollow rib, eectually prevents any warp or sag of the plate.

I claim as new and of my invention- A top-plate for a stove or range, having cast solidly to its under side the hollow stiffening piece or rib B having one or more inlets in the cooler portion of the fire-space and one or more outlets in the hotter portion ot the same, substantially as and for the purpose set forth.

.In testimony ot which invention I hereunto set my hand.

JOHN VAN.
